It's normal: this line is superfluous since it just repeats the default
setting of \.  Instead of removing it, you want to replace it with another
line such as

   (modify-syntax-entry ?\\ "." rexx-mode-syntax-table)

where the "." means "punctuation".  See C-h f modify-syntax-entry RET
for a bit more documentation.
